The latest in the line of Cat D6N dozers combines well-known versatility with a range of technology features to give you more job site productivity than ever before. A new transmission with lock-up clutch torque converter delivers ease of operation, increased net power, plus a 10-15 percent improvement in fuel efficiency. The D6N has the weight and horsepower you want for dozing applications and the balance and stability you need for finish grading – all in one easy-to-transport machine. The D6N meets U.S. EPA Tier 4 Final/EU Stage IV/Korea Tier 4 emission standards.

Power and Performance

A Cat C7.1 ACERT engine gives you the power and reliability you need. Improved fuel economy over the previous model and efficient use of Diesel Exhaust Fluid (DEF) gives you excellent overall fluid efficiency.

An optional manually reversing fan is available for high debris conditions, and an optional sand blast grid can help protect the radiator from abrasive materials and debris.

Lock-Up Clutch

A new transmission with a lock-up clutch torque converter gives you the performance of direct drive with the ease of operation of power shift. Transmission controls will automatically select the drive mode best suited to your application, providing increased productivity and efficiency.*

Enhanced Auto Shift

Standard Enhanced Auto Shift helps you save fuel by automatically upshifting/downshifting to maintain the most efficient gear based on load. Three different settings – 3-speed, 6-speed and fine adjustment mode – allow you to optimize tractor performance to match material and job site conditions.

Differential Steering

Differential Steering maintains full power to both tracks for best-in-class turning, even with a full blade load. When one track speeds up, the other slows down an equal amount, so you have better maneuverability and faster cycle times. Load capacity, power and speed control are also better when working in soft conditions.

Load Sensing Hydraulics

Field-proven system senses the load and continuously adjusts hydraulic power to your blade to maximize efficiency.

*Compared to the previous D6N model.

Operator Environment

Roomier cab with a wider entry offers added comforts like a heated/ventilated seat option, manually adjustable armrests, larger cup holder and auxiliary power port. Smoother shifting and a quieter engine add to overall operator comfort. Modified cab seals and ducts help improve heating and air conditioning performance, and a redesigned cab/fresh air filter helps keep the cab cleaner. A color LCD display shows vital operating information, as well as Slope Indicate real-time machine mainfall and cross slope. A grade control display can be integrated right into the dash so data is available at a glance.

Implement and Steering Controls

Machine direction, forward/reverse shifting and gear selection are all combined into a single tiller control located on the left armrest.

Standard Electro-hydraulic controls are designed for low effort. Operators have precise control of the blade and rear attachments, as well as the functions of a 6-way VPAT blade.

Integrated Technologies

Cat Connect makes smart use of technology and services to improve your job site efficiency. Using the data from technology equipped machines, you’ll get more information and insight into your equipment and operations than ever before.

Cat Grade Control Slope Assist (S) helps operators more easily achieve the required main-fall and slope orientation of the blade by automatically maintaining pre-established blade angles for the grade. The system saves time, increases finish quality and reduces operator input. Experienced operators can work more productively and less experienced operators can achieve better quality results more quickly.

Cat Grade Control 3D (O – available early 2016) is an integrated grade-control system that enables operators to improve grading efficiency, accuracy, and productivity in both production dozing and fine-grading applications. The integrated design positions antennas on the cab roof, eliminating conventional blade-mounted masts and related cables. The AccuGrade Ready Option (ARO) is part of the package for added versatility, and AutoCarry™ is included to further boost productivity.

Cat AccuGrade (O) is a dealer-installed aftermarket grade-control system that provides increased grading versatility and the ability to scale capacity to changing needs, providing a choice of lasers for 2D flat-plane and slope work, Global Navigation Satellite System (GNSS) control for complex 3D cuts and contours, and/or systems using a Universal Total Station (UTS) for fine and finish grading.

Selective Catalytic Reduction utilizes Diesel Exhaust Fluid (DEF), which can be conveniently refilled when you refuel. The DEF fill nozzle is located next to the fuel tank, with easy access via a rear step. A tone will sound (with key on), when the tank is nearly full and a gauge on the dash shows your fluid level. The system is designed to use one tank of DEF for each tank of fuel (1:1 DEF fill ratio). The D6N typically has used DEF at a rate of 2-3 percent of fuel consumption.

When the machine is turned off, a pump will automatically purge the DEF lines to help prevent freezing. A symbol on the dash and a light/symbol on the Ground Level Service Center indicate when the purge is complete and that it is safe to turn off the electrical disconnect. If the engine/aftertreatment temperatures are high, a Delayed Engine Shutdown will activate automatically to cool the machine and then purge the lines. For complete aftertreatment information, please refer to your machine’s Operation and Maintenance Manual.

Equipped for the Job

Choose Heavy Duty undercarriage for aggressive applications like land clearing, side-slopes or rocky terrain. Or, choose SystemOne™ undercarriage that is designed to work and wear as a system for longer life and lower costs in abrasive or low/moderate impact applications. A broad choice of track shoe designs and widths help you further optimize your machine for performance and longer life.

Blades

Semi-Universal and Straight blades are designed with a strong box section to stand up to the most severe applications. Heavy moldboard construction, hardened bolt-on cutting edges and end bits add strength and durability.

The Variable Pitch Angle Tilt (VPAT) blade allows you to hydraulically adjust lift, angle and tilt for precise results. The VPAT blade is wider to take on a variety of applications so you can use your D6N for spreading material, finish grading, side casting, V-ditching and backfilling. An optional folding VPAT blade is available to reduce overall machine width to more easily meet transport requirements.

Rear Implements

To help you match your D6N to the task at hand, you can outfit your D6N with a multi-shank ripper, winch or drawbar.

Ask your Cat dealer for available options to help you optimize your machine for the work you do.

A standard Operator Presence detection system allows the machine to idle when the operator is not seated, but locks out the power train and front and rear implements to avoid unintentional movement.

New seat belt indicator enhances safety by reminding the operator to buckle up with a light/alarm. Once the machine is in gear, a fault code will register through Product Link if the operator fails to fasten the seat belt.

Serviceability and Customer Support

The D6N is designed to help you get routine service done quickly and efficiently so you can get to work.

A two piece engine enclosure door, flip latches and a panel you can remove without tools gives you easy access to service points. Grease points are grouped and located in the engine compartment as well, so they are protected but still allow you to get to them quickly. The radiator door is hinged for easy cleanout access.

Electrical disconnect, hour meter and the remote lighting access switch are accessible from ground level on the left side of the machine. Hydraulic service points are grouped on the right side of the machine. And for quick undercarriage cleanouts, a new lockable shovel mounting bracket has been added to the back of the machine.

An automatic hydraulic valve lash eliminates the need for manual adjustment, saving you time and money on engine maintenance.
